History
Kokubu Station was opened on 24 November 1929 by the Railway Ministry, taking its name from the neighbouring earlier-built Kokubu Station which was simultaneously renamed (first to Nishi-Kokubu, then to Hayato). The connecting Ōsumi Line was completed from Kaigata Onsen on 9 September 1972, making this a junction. Freight handling ended on 1 February 1984 and parcel service on 14 March 1985. The Ōsumi Line was abolished in its entirety on 14 March 1987, and on 1 April 1987 the station passed to JR Kyushu at privatisation. SUGOCA service began on 1 December 2012, barrier-free works including two elevators were completed on 2 May 2018, and on 1 October 2023 the station was returned from outsourced operation to direct JR Kyushu staffing.
